Reducing home electricity bills by about 50% ?

Can I reduce my home electricity bill by about 50% by using the following method :-

Use an inverter to power an electric motor, the shaft of the electric motor rotates the armature of a AC generator with high number coils and powerful neodymium magnets. The generator recharges the inverter.

The biggest energy hog is your air conditioner. If you can reduce your attic temperature from the normal summer average of 145F to about 100F... then your air conditioning bill will be greatly reduced 30 to 50 percent. This can be done by painting your roof white (using Hydrated Lyme) ...so it is 85 % reflective. Or by placing styrofoam sheets on the attic ceiling so the heat goes up and out your roof-turbines. I have done BOTH of these things to my house and our electric usage went from about 840kW per month (summer ) down to about 591 kW per month. Here are my actual monthly usage readings:

Here is the RAW DATA for my home electricity usage for the years 2006 through 2010:

You mean opening the windows at night and closing them during the day, and sleeping in the buff I presume ;-)

I had a window unit for one season, but aside from that, for the past 52 years I've done just fine without. Helps to live in Northern Ohio I suppose, but I am a big believer in human acclimation as the best way to deal with heat...although in the defense of average folk, business tends to spoil that for many who work in offices and retail spaces)

One other thing very green thing that can be done is grow trees to cover the roof with their canopy, but that is, unfortunately, not something most people can do in a very short period of time).

Alternatively, instead of building a new home, one *could purchase any one of millions of older homes nearer to city centers that are now going to rot due to the neuvo-riche mentality of destroying farmland for their own 1.4 acres of cardboard housing on someone's old corn field 15-20 miles from their places of employment...

DeVry is a great staring point for robotics. A campus in almost every state. Search out the one closest climate to your homeland.

It is possible to teach yourself programming. And buy a toy robot ( toys are excellent examples of engineering know how ) to take apart understand, put back together, give to a child then get a different robot and repeat the process

I went to I.I.T. ( Illinois Institute of Technology ). That was 50 years ago. The admission process has certainly changed since then with the PC.

I worked for Skilsaw a drill manufacturer in Chicago as a jumior EE for one semester and attended IIT the next semester back and forth for 7 years. At skillsaw we were diffusing our own power SCRs for speed control drill motors. At IIT the lab was 10 years behind we built ring counters using discrete devices, when RTL ICs were already available. The point is college taught me math, programming and how to look up a subject in library ( that is all ). DeVry is a "hands-on" institution.

My heavy machine experiences were in a high school vocational 2 yr lab.

A good deal of my knowledge has been acquired from expert people that I worked with in different companies in the US.

Good, there ya go. The REAL ways to reduce your power bills are to reduce consumption (see the bazillions of suggestions on here), or if you're really obsessed, to generate your own power through solar, wind, or a hydroelectric stream, all of which involve substantial initial investment.

There is no free energy. There is no perpetual motion. If they're claiming either, they're lying or deluded.

There *MIGHT* be a new source of energy. But that would be an extraordinary claim, which would require extraordinary proof, and if they had that proof they'd be going very public with it rather than trying to find suckers.

If you have a stream on your property with sufficient flow, you could employ a turbine generator. If you use an electric dryer (clothes) you can redirect the flow back into the house (through a filter) during the cold months to reduce your heating bill. You can also allow the off-flow from a load of laundry wash to stand for a while to recover some of the heat from the water (presuming it's warm or hot water in the splash basin...you just have to remember to let it drain before the next load or after it has cooled. for forced air homes during the winter, this also acts as a humidifier...

If you can afford it or have the technical know-how and associated parts and tooling, you can buy or build a wind turbine to generate a bit of power.

Vinet, some people have been promoting these magical perpetual motion schemes for years to people who are naive. They sound good at first glance, but they simply don't work. (friction alone would gobble up the power with time)

IMO, when you hear someone adamantly saying things like "yeah, they works, but the evil (insert powers-that-be) have hidden the patents, killed the inventors, etc. etc... tripartite conspiracy...blah blah...", you should eye them with a high degree of skepticism, if not outright disdain.

It's simply a load of hooey and defies physics.

As a point of note, Regenerative braking, however is not, since what people are doing there is recovering energy during a braking phase that would otherwise just be dissipated as heat. (for instance, diesel locomotives have been employing that trick for 70 or 80 years, using generators in the braking system to "steal" energy and act as the primary brakes)...and just in case you weren't aware, diesel locomotives actually run on electricity. that's what the diesels produce. (afaik, the car sitting just behind the diesel houses the generators and batteries)

What???? You mean all of those Hollywood movies about runaway trains are not based on reality!!! Impossible!! All script writers are at least grade school graduates so they could never make up something that wasn't actually based on the science and engineering that they never had a clue about.

I wonder if they could make it a requirement that there has to be a disclaimer at the start of those shows. "Warning -- that facts depicted as true science are in fact not true and are based on a fantasy world where things that cannot possible happen do."

Note that your PC is also a pretty big energy hog, especially if you leave it running 24/7, and most especially if it's an older model. If it isn't doing something useful, shut it down or let it hibernate.

As he left the blazing summer heat outside the Warlock'scave, the visiting sorceror sghied with pleasure. "Warlock,how can you keep this place so cool? The mana in thisregion has decreased to the point where magic is nearlyimpossible."The Warlock smiled and so did the unnoticable man youngman who was sorting the Warlock's parchements in a cornerof the cave. The Warlock said "I used a small demonHarlaz. He was generated by a simple, trivial spell. Hisintelligence is low---fortunately, for his task is a dull one.He sits at the enternce to this cave and prevents the fast-moving molecules of air from entering and the slow-movingmolecules from leaving. The rest he lets pass. Thus the caveremains cool" "That's marvelous, Warlock! I suppose the process canbe reversed in winter?" "Of course." "Ingenious." Oh, I didn't think of it, " the Warlock said hastily."Have you met my clerk? It was his idea." The Warlockraised his voice. "Oh, Maxwell... Larry Niven

Heh, try driving an EV around, you get some brilliant suggestions. Mount a wind turbine on top, put the alternator on just one wheel (so it only uses a *little* energy), etc. I've learned soooo many ingenious ways to be completely and utterly wrong. :P

Even thought it appears to be, not even the earth is in perpetual motion. It slows down just a tiny bit each year. So the years are always getting longer. Friction, entropy, the gravitation of other bodies, they all drain away energy. Unless you put more in, every system slows down. Researchers have come very close though, An electrical current induced in a superconductor at a fraction above absolute zero circulates almost indefinitely. However the process of trying to measure it also kills it. And that brings up another point, The simple act of measuring the energy of a system drains energy from the system. Its the laws of the universe and you can;t win against it.

BTW, if you want to understand more about why over-unity -- and even perpetual motion -- doesn't work, and many of the ways people have tried to achieve that, I strongly recommend the Museum of Unworkable Devices:
